Technical Data Sheet LOCTITE TCF 4000PXF October -2014 PRODUCT DESCRIPTION THERMAL RESISTANCE vs. MOUNTING PRESSURE LOCTITE TCF 4000 PXF provides the following product characteristics: Technology Phase Change Appearance Gray Application Method Manual application Product Benefits Low thermal resistance Non silicone No pump-out, dry-out or pull-out Phase change temperature 45 C Application Thermal management Typical Assembly Thermal grease replacement in Applications computing applications , Lidded and bare die processor applications and Used between any heat generating electrically isolated component and a heat sink LOCTITE TCF 4000 PXF is a reworkable phase change thermal interface material suitable for use between a heat sink and variety GENERAL INFORMATION heat generating components .The material flows at the phase change For safe handling information on this product, consult the temperature, conforming to the surface features of the components . Material Safety Data Sheet, (MSDS). Upon flow, air is expelled from the interface, reducing thermal impedance, performing as a highly efficientthermal transfer material . Custom parts are also available upon request with low cost tooling . DIRECTIONS FOR USE 1. This product is packaged as a free-standing filmbetween two release liners and is supplied as a diecut preform to match a TYPICAL PROPERTIES wide variety of applications . PXF-8 2. Currently supplied in two compound thicknesses, multiple Thermal Impedance ,ASTM D5470: thicknesses will soon be available to match surface finishes and 2 20 psi ,C-in /W 0.015 flatness considerations in the interface area . 2 80 psi ,C-in /W 0.008 3. LOCTITE TCF 4000 PXF is completely reworkable without Compound Thickness Before Phase Change : solvents and is easier to remove than previous formulations . Inches 0.008 4. Ifa clean surface is required, any compound present can easily (mm) (0.2) be removed with mineral spirits. No silicones are utilized in the formulation of the phase change compound . Thermal Conductivity ,W/(m-K) 3.4 5. Unlike previous versions of Powerstrate, LOCTITE TCF 4000 PXF does not require adhesive edge strips for heatsink attach Viscosity Above Phase Change Temp thixotropic applications. Thetack nature of the product allows for it to naturally adhere to the heatsink surface . PXF-16 Thermal Impedance ,ASTM D5470: 2 Storage 20 psi ,C-in /W 0.023 2 Store product in the unopened container in a dry location. 80 psi ,C-in /W 0.019 Storage information may be indicated on the product container Compound Thickness Before Phase Change : labeling. Inches 0.016 (mm) (0.4) Optimal Storage: 23 C. Storage greater than 40 C can Thermal Conductivity ,W/(m-K) 3.4 adversely affect product properties.
